The second group will undergo daily bedside arthrocentesis. The involved joint will be prepped and draped in a sterile fashion prior to every aspiration. As much infected joint fluid will be removed as possible. Each aspirated fluid will be evaluated for gross appearance, cell count, gram stain and culture, glucose concentration, and crystal analysis. Arthrocentesis will be performed daily until effusion resolves or until aspirate no longer yields a purulent exudate.
